Just Vanish

Once a staff member vanishes, the server hides that player from entity tracking, the tab list and the player list. Mobs ignore vanished players and existing targets are cleared, while command selectors no longer reveal them. Chat messages, system messages and join or leave notices that would identify a vanished player are concealed from unauthorized viewers, and the player's direct sounds, step sounds, particles and animations are suppressed.

Only the server needs the mod, so regular players join without installing anything. Players who vanish keep that state after dying, reconnecting or a server restart. Other server mods can query the vanish state or listen for the PlayerVanishEvent on the NeoForge event bus, and an optional personal VANISHED boss bar can be shown. The mod is released under All rights reserved and is not open source, although its source code and issue tracker are public. It is published for NeoForge on 1.21.1 only, with the latest file 1.3.2 from 2026-08-15, and it runs alone or beside another vanish mod.
